PowrBeast part 0555596 is a foot valve ball designed to create a one-way seal in the foot valve assembly on compatible PowrBeast 4700, 7700, and 9700 sprayers. This precision ball allows material to enter the pump suction line while preventing backflow when the pump is not operating. Replacing a worn, corroded, or damaged foot valve ball restores proper priming capability and prevents material drain-back.

The 0555596 Foot Valve Ball is a precision spherical component used in the foot valve assembly of compatible PowrBeast 4700, 7700, and 9700 sprayers. It acts as a check valve, allowing material to flow into the suction line while preventing backflow when the pump stops.
The foot valve is located at the bottom of the suction tube and is critical for maintaining pump prime. When the pump operates, suction lifts the ball off its seat, allowing material to enter. When the pump stops, gravity and back-pressure seat the ball, sealing the line and preventing material from draining back into the supply container. This ensures the pump remains primed and ready for immediate operation when restarted. The ball must be perfectly spherical and smooth to create a reliable seal with the valve seat.
Over time, foot valve balls can become worn, corroded, or develop flat spots that prevent proper sealing. A worn or damaged ball can cause loss of prime, requiring repeated priming and reducing productivity. It may also allow material to drain back, creating mess and waste. Replacing the foot valve ball restores proper one-way sealing, ensures reliable priming, and prevents material drain-back.
| One-way flow | Allows material to enter suction line, prevents backflow |
|---|---|
| Prime retention | Maintains pump prime when not operating |
| Check valve sealing | Seals against valve seat to stop flow |
| Loss of prime | Pump requires frequent re-priming |
|---|---|
| Material drain-back | Fluid drains from suction line when pump stops |
| Visible wear | Ball is pitted, scored, or has flat spots |
| Corrosion | Surface damage from chemical exposure |

When replacing the foot valve ball, these associated components are often inspected or replaced at the same time.
The surface the ball seals against; inspect for wear or damage.
The housing that contains the ball and seat; check for damage.
Inspect the suction line for cracks or restrictions.
